Thevirtualspecifier specifies that a non-staticmember functionisvirtualand supports dynamic dispatch. It may only appear in thedecl-specifier-seqof the initial declaration of a non-static member function (i.e., when it is declared in the class definition). ...
class Derived : public Base { public: // function prototype void print() override; }; // function definition void Derived::print() { // code }Here, void print() override; is the function prototype in the Derived class. The override specifier ensures that the print() function in Base ...
The operation to create or update a virtual machine. Please note some properties can be set only during virtual machine creation.
class C : public A, public B { using A::foo; }; int main() { B b; b.foo(); // OK: B::foo() C c; c.foo(); // error: A::foo() or private member in class 'C' return 0; } Virtual Functions When we talk aboutvirtual functionorvirtual method, it's always in the co...
It is possible that you want to include a virtual function in a base class so that it may be redefined in a derived class to suit the objects of that class, but that there is no meaningful definition you could give for the function in the base class. We can change the virtual function...
pure virtual function allows you to put a member function in an interface without being forced to provide a possibly meaningless body of code for that member function. At the same time, a pure virtual function forces inherited classes to provide a definition for it. ...

Of course the definition of the inline virtualprintfunction must appear somewhere in the executable for the code to run properly. That is, at least one definition is necessary in order for its address to be placed within the virtual table. How does the compiler decide when to generate that ...
